I can't see the files and folders created via api in my Google Drive using php

Question

I am trying to create folder using google drive api. I am able to get file id at the end. but i am not able to my folder in google drive. it seems some permission issue?

$scopes = array(
    'https://www.googleapis.com/auth/drive',
    'https://www.googleapis.com/auth/drive.appdata','https://www.googleapis.com/auth/drive.apps.readonly',
    'https://www.googleapis.com/auth/drive.metadata','https://www.googleapis.com/auth/drive.file',
    'https://www.googleapis.com/auth/drive.readonly','https://www.googleapis.com/auth/drive.photos.readonly'
);
$creds = new Google_Auth_AssertionCredentials(
    $serviceAccountName,
    $scopes,
    file_get_contents($keyFile)
);
$client = new Google_Client();
$client->setApplicationName($appName);
$client->setClientId($clientId);
$client->setAssertionCredentials($creds);
$service = new Google_Service_Drive($client);
$fileMetadata = new Google_Service_Drive_DriveFile(array(
  'name' => 'Invoices',
  'permissions' => array('type'=>'anyone','role'=>'reader','allowFileDiscovery'=>1),

  'mimeType' => 'application/vnd.google-apps.folder'));
$file = $service->files->create($fileMetadata, array());

printf("File ID: %s\n", $file->id);

Answer 1

The files that are being created belong to the API account email (something like [email protected]. If you go to the drive URL: https://docs.google.com/document/d/{ID}, you will get a "Permission Denied, request access" page.

The service account email is not related to your user email.

In order to create files with your user, you need to create an OAauth token authorization.

1. Create the OAuth credentials following the steps "Step 1: Turn on the Drive API" on this page

2. Modify your script, by following the example on this page, you can have:

---

use Google_Client;
use Google_Service_Drive;
use Google_Service_Drive_DriveFile;

...

$file = 'root/to/your/credentials.json';

$client = new Google_Client();
$client->setScopes([
    'https://www.googleapis.com/auth/drive',
    'https://www.googleapis.com/auth/drive.appdata',
    'https://www.googleapis.com/auth/drive.apps.readonly',
    'https://www.googleapis.com/auth/drive.metadata',
    'https://www.googleapis.com/auth/drive.file',
    'https://www.googleapis.com/auth/drive.readonly',
    'https://www.googleapis.com/auth/drive.photos.readonly'
]);

$client->setAuthConfig($file);
$authUrl = $client->createAuthUrl();

printf("Open the following link in your browser:\n%s\n", $authUrl);

// You will need to open this url
print 'Enter verification code: ';
$authCode = trim(fgets(STDIN));

$accessToken = $client->authenticate($authCode);

file_put_contents($credentialsPath, $accessToken);
printf("Credentials saved to %s\n", $credentialsPath);

$client->setAccessToken(json_decode($accessToken, true));

$service = new Google_Service_Drive($client);

$metadata = new Google_Service_Drive_DriveFile([
    'name' => 'testing drive',
    'mimeType' => "application/vnd.google-apps.document"
]);
$file = $service->files->create($metadata, []);
print_r($file);

---

The file should be in your Drive home directory.

By the way, I suggest you try the new version google/apiclient:2.0.2 (which is still on Beta, but works okay).

Answer 2

Mayrop answer is partially right.

The files that are being created belong to the API account email (something like [email protected].

You need to give permission to owner of that account like

    $newPermission = new Google_Service_Drive_Permission();
$value="email id";
$type="user";
$role="writer";
  $newPermission->setValue($value);
  $newPermission->setType($type);
  $newPermission->setRole($role);
 try {
   $res= $service->permissions->insert($fileId, $newPermission);
    print_r($res); 
  } catch (Exception $e) {
    print "An error occurred: " . $e->getMessage();
  }

You will see that folder in Shared with me. You can also add in your drive manually.

You can also disable sending notification via email using

$service->permissions->insert($fileId, $newPermission,array('sendNotificationEmails'=>false));

Hope this will work for you.
